Recently, Google Messages users have been encountering strange encrypted text messages that appear as gibberish characters. These messages, which cannot be deciphered, seem to contain legitimate links to Google support pages. The influx of comments on a Reddit thread discussing these messages suggests that this issue is widespread and has been reported by users globally.
One theory is that these encrypted messages may be originating from malfunctioning spambots. These spambots could be trying to identify and collect active phone numbers by sending messages with the intention of gathering read receipts. The fact that the messages come from unknown senders and fail to decrypt properly points to a potential bot malfunction.
While it is unclear what the exact purpose behind these messages is, they do not appear to be related to any zero-day RCS exploit. Users are advised to refrain from interacting with these messages and are encouraged to report them using Google Messages’ built-in reporting tool. Until Google provides more information on this issue, vigilance is key in dealing with these suspicious messages.
